[Transverse Colectomy with D2 Lymph Node Dissection with a Small Incision Using Body Surface 3D-Simulation CT Colonography].

Background: Laparoscopic transverse colectomy is technically difficult. In mini-laparotomy surgery, colectomy for midtransverse colon cancer can easily be performed, but exact D2 lymph node dissection is very difficult for a variety of vessels in the transverse colon. Using 3D-CT imaging, we present a case of D2 lymph node dissection where mini-laparotomy transverse colectomy was performedby a small incision similar to that usedin laparoscopic surgery.

[D2 Lymph Node Dissection in Mini-Laparotomy Transverse Colectomy Using Non-Contrast Simulation CT Colonography].

Background And Purpose: It is reported that simulation computed tomography colonography(S-CTC), which combines CTC and 3-dimensional(3D)vascular imaging, is useful in colorectal cancer surgery. However, it is difficult to create 3D vascular images using non-contrast CT. Laparoscopic transverse colectomy is said to be technically difficult.

[Optimal Dissection of the Intestinal Tract and Preservation of Vascular Supply in Left Hemicolectomy Using Simulation Computed Tomography Colonography].

Left hemicolectomy is a standard surgical method for cancer of the descending colon. Resection involves the region from the left side of the transverse colon to the sigmoid colon. Although laparoscopic hemicolectomy is widely used, it is difficult to determine an appropriate resection range during surgery because of the limited visual field.

Gastric Resection Under Retroflexed Endoscopic Guidance: A Reliable Procedure for Totally Laparoscopic Subtotal Gastrectomy.

Background/aims: Totally laparoscopic distal gastrectomy (TLDG) has become a feasible and safe surgical option for early gastric cancer. However, determining the transection line of the stomach without palpation is still difficult. This study aimed to assess the efficacy of TLDG for gastric resection under retroflexed endoscopic guidance (GRREG) in patients with gastric cancer in the middle third of the stomach.

[Surgical Simulation-CT Colonography for Laparoscopic Assisted Sigmoid Colectomy Preserving the Inferior Mesenteric Artery and Vein].

D2 lymph node dissection in laparoscopic surgery for early colon cancer requires selective vessel dissection, making it technically very difficult. Using surgical simulation-CT colonography (simulation-CTC), we could perform laparoscopic assisted sigmoid colectomy preserving the inferior mesenteric artery (IMA) and vein (IMV) more accurately and safely. The case described here was a type 0-Ip sigmoid colon cancer with a tumor size of 13 mm.

In situ surgical procedures for locally advanced pancreatic cancer: partial abdominal evisceration and intestinal autotransplantation.

Background/purpose: Pancreatic cancers in which invasion to the root of the mesentery are suspected have been regarded as unresectable in general. We report the surgical techniques in two cases of locally advanced pancreatic cancer for which in situ surgical procedures including partial abdominal evisceration and intestinal autotransplantation were performed.

Methods: The patients were a woman 57 years of age and a man 64 years of age.

Is pancreatectomy with arterial reconstruction a safe and useful procedure for locally advanced pancreatic cancer?

Background/purpose: We often encounter unresectable pancreatic cancer due to invasions of the major vessels. Vascular resection for locally advanced pancreatic cancers has an advantage in en block local resection. There are potential cases in which good outcomes can be achieved by arterial resection.

Pancreatectomy with reconstruction of the right and left hepatic arteries for locally advanced pancreatic cancer.

Background/purpose: The resectability of locally advanced pancreatic cancer depends upon, before anything else, the relationship between the tumor and the adjacent arterial structure. Pancreatic cancer that has developed at the caudal side of the pancreas can invade the common hepatic artery (CHA). Pancreatic cancers with CHA involvement can become candidates for surgery in selected cases.

The blood supply of the hilar bile duct and its relationship to the communicating arcade located between the right and left hepatic arteries.

Background: There is an increasing demand for living donor liver transplants. However, the biliary complication rates are still high.

Methods: The anatomy of the communicating arcade (CA) between the right and left livers and its relevance to the blood supply of the hilar bile duct was evaluated using adult cadaveric livers and cast specimens.

Nucleotide sequence and genetic structure of a novel carbaryl hydrolase gene (cehA) from Rhizobium sp. strain AC100.

Rhizobium sp. strain AC100, which is capable of degrading carbaryl (1-naphthyl-N-methylcarbamate), was isolated from soil treated with carbaryl. This bacterium hydrolyzed carbaryl to 1-naphthol and methylamine.
